|
|
Guys,
anyone know what the HM in HFQ 900 HM means?
I asked the seller from which projector they came from.
He said from a Barco Reality 909.
did Barco offer a wider range of HFQ 900 lenses on the 909 series ?
the auction photos show the sticker saying HFQ900 HM on them
Thanks
Michael

Hmmmmmm.... nope, no idea! 
I know that some of the RUnco DRV 1200s used a lower end lens, the Runco 'unmarked' one, which I suspect is a GT17, but the Barco sets used the HFQ900.
If the front barrel of the lens is plastic, then you have the correct high end lenses.

I saw what you did there Curt..... hmmmm
Could it have something to do with the throw. Only thing I can think of and really the only variable that you'd want to offer on CRT lenses. Maybe a lens for an unusual installation like SEOS.
Thats a premium price he's asking.
